I've published a package called FindAgain to the Cincom public Store
repository. It allows you to search for senders of a selector or
references to a class or shared variable (which you could do before) and
when you select one, find subsequent references to that selector or
variable in the method (which you couldn't do before). The Code Tool's
popup menu in the Browse Senders or Browse References windows will have
two new menu items called Find Next and Find Previous. If there is more
than one reference to the selector or variable in the method, Find Next
will be enabled to allow you to find the next reference. Once you reach
the last reference, Find Next is disabled. Once you use Find Next, the
Find Previous menu item will be available until you hit the first reference.
This code is released without restrictions and without warranty. Use it
for whatever purpose you wish. If it doesn't work for you, fix it and
publish your fixes.
